Spot Kill® and Spot Kill® WP

Do all algicides kill algae?

Not all algicides are alike, only algicides that have been approved by the EPA for killing algae actually perform. All BioGuard products have been thoroughly reviewed and proven effective. Various kinds of algae may require different treatments to ensure they are eliminated.

Especially effective on black algae growth

Spot Kill WP is for white plaster pools only (do not use on any bleachable surfaces)
